Caladium plant named ‘RFL BRZ OF13-1082’

ABSTRACT

A new and distinct cultivar of  Caladium  plant named ‘RFL BRZ OF13-1082’, characterized by its intermediate to tall height; upright and mounding plant habit; dense and bushy appearance; vigorous growth habit; rapid growth rate; fancy-type leaves that are mostly greyed red in color, randomly mottled with dark green flushed with greyed red-colored blotches and randomly dotted with light red-colored spots; and leaf petioles that are light greyed orange to light greyed red in color with numerous dark greenish brown-colored stippling and streaks.

Botanical designation: Caladium X hortulanum.

Cultivar denomination: ‘RFL BRZ OF13-1082’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Caladium plant, botanically known as Caladium X hortulanum, commercially referred to as a fancy leaf-type Caladium and hereinafter referred to by the name ‘RFL BRZ OF13-1082’.

The objective of the Inventor's breeding program is to create new Caladium plants that have uniform plant habit, exceptional container and garden performance and attractive and unique leaf coloration.

The new Caladium plant originated from a cross-pollination made by the Inventor in April, 2012 in Avon Park, Fla. of Caladium X hortulanum ‘Red Flash’, not patented, as the female, or seed, parent with Caladium X hortulanum ‘Twist N' Shout’, not patented, as the male, or pollen, parent. The new Caladium plant was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Zolfo Springs, Fla. in September, 2013.

Asexual reproduction of the new Caladium plant by “chipping” the tubers (cutting the tuber into segments with each segment containing an axillary bud and tuber cortical tissue) in a controlled outdoor nursery environment in Zolfo Springs, Fla. since April, 2014 has shown that the unique features of this new Caladium plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Caladium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘RFL BRZ OF13-1082’. These characteristics in combination distinguish ‘RFL BRZ OF13-1082’ as a new and distinct Caladium plant:

-   -   1. Intermediate to tall in height and upright and mounding plant         habit; dense and bushy appearance.     -   2. Vigorous growth habit and rapid growth rate.     -   3. Fancy-type leaves that are mostly greyed red in color,         randomly mottled with dark green flushed with greyed red-colored         blotches and randomly dotted with light red-colored spots.     -   4. Petioles that are light greyed orange to light greyed red in         color with numerous dark greenish brown-colored stippling and         streaks.

Plants of the new Caladium differ primarily from plants of the female parent, ‘Red Flash’, in the following characteristics:

-   -   1. Plants of the new Caladium grow much faster than plants of         ‘Red Flash’.     -   2. Plants of the new Caladium and ‘Red Flash’ differ in leaf         color as leaves of plants of the new Caladium are mostly greyed         red in color, randomly mottled with dark green flushed with         greyed red-colored blotches and randomly dotted with light         red-colored spots whereas leaves of plants of ‘Red Flash’ have         red-colored venation and interveinal areas with pink and         white-colored spots and dark green-colored borders.     -   3. Plants of the new Caladium and ‘Red Flash’ differ in leaf         petiole color as petioles of the new Caladium are light greyed         orange to light greyed red in color with numerous dark greenish         brown-colored stippling and streaks whereas petioles of plants         of ‘Red Flash’ are red pink to tan pink in color with         darker-colored stippling, stripes and tessellations.

Plants of the new Caladium differ primarily from plants of the male parent, ‘Twist N' Shout’, in the following characteristics:

-   -   1. Plants of the new Caladium and ‘Twist N' Shout’ differ in         leaf color as leaves of plants of the new Caladium are mostly         greyed red in color, randomly mottled with dark green flushed         with greyed red-colored blotches and randomly dotted with light         red-colored spots whereas leaves of plants of ‘Twist N' Shout’         are olive green in color with green to coppery bronze-colored         venation and coppery orange-colored spots and blotches.     -   2. Plants of the new Caladium and ‘Twist N' Shout’ differ in         leaf petiole color as petioles of the new Caladium are light         greyed orange to light greyed red in color with numerous dark         greenish brown-colored stippling and streaks whereas petioles of         plants of ‘Twist N' Shout’ are light green in color.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘Burning Heart’, disclosed in U.S. Plant Pat. No. 27,071. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘Burning Heart’ in the following characteristics:

-   -   1. Plants of the new Caladium and ‘Burning Heart’ differ in leaf         color as leaves of plants of the new Caladium are mostly greyed         red in color, randomly mottled with dark green flushed with         greyed red-colored blotches and randomly dotted with light         red-colored spots whereas leaves of plants of ‘Burning Heart’         are bronze in color with contrasting salmon orange-colored         spots.     -   2. Plants of the new Caladium and ‘Burning Heart’ differ in leaf         petiole color as petioles of the new Caladium are light greyed         orange to light greyed red in color with numerous dark greenish         brown-colored stippling and streaks whereas petioles of plants         of ‘Burning Heart’ are greyed green flushed with greyed red in         color with brown-colored stippling, streaks and tessellations.

Plants of the new Caladium can be compared to plants of Caladium X hortulanum ‘John Peed’, not patented. In side-by-side comparisons, plants of the new Caladium differ primarily from plants of ‘John Peed’ in the following characteristics:

-   -   1. Plants of the new Caladium grow much faster than plants of         ‘John Peed’.     -   2. Plants of the new Caladium and ‘John Peed’ differ in leaf         color as leaves of the new Caladium are mostly greyed red in         color, randomly mottled with dark green flushed with greyed         red-colored blotches and randomly dotted with light red-colored         spots whereas leaves of ‘John Peed’ have dark red-colored         centers and red-colored venation with dark green-colored         margins.     -   3. Plants of the new Caladium and ‘John Peed’ differ in leaf         petiole color as petioles of the new Caladium are light greyed         orange to light greyed red in color with numerous dark greenish         brown-colored stippling and streaks whereas petioles of ‘John         Peed’ are dark pink with dark green to almost black-colored         stippling and streaks.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 15-cm containers in a polypropylene-covered shadehouse (30% light reduction) in Avon Park, Fla. and plants grown in ground beds under full sunlight conditions in an outdoor nursery in Crewsville, Fla. The plants were grown under cultural practices typical of commercial shadehouse and outdoor nursery production. During the production of the shadehouse-grown plants, day temperatures ranged from about 28° C. to 33° C., night temperatures ranged from about 22° C. to 25° C. and light levels were about 8,000 foot-candles. During the production of the outdoor nursery-grown plants, day temperatures ranged from about 29° C. to 35° C., night temperatures ranged from about 23° C. to 26° C. and light levels ranged from 10,000 to 12,000 foot-candles. Plants grown in the shadehouse were seven weeks old and plants grown in the outdoor nursery were seven months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
